Japanese: What Japanese Culture Surprised You?

A new movie called "ダーリンは外国人(my darling is a foreigner)" is coming soon in Japan. This was originally a comic book about this international couple living in Japan. The Japanese woman, Saori doesn't speak English, but her American husband, Tony, who is a "language geek" speaks Japanese super fluently. The story is basically their daily lives in Japan, but it's really funny.

Along with the movie, they interviewed some international couples in Japan.

The topic was "What Japanese culture " surprised you?

I can have my students catch what the people are saying, and have 
them talk about it. Also if there are some students who have been 
to Japan, they can share their experiences.
